O the culture media markedly and specifically increased cell migration levels in human neoplastic astrocytes, and that these effects were related to striking modifications in the organization of the actin cytoskeleton and an increase in small GTPase RhoA expression [33]. Conversely, knocking down galectin-1 expression in U87MG GBM cells by stable transfection with antisense galectin-1 mRNA, the co

File1: Figure S1. Galectin-1 staining correlates with patient survival. Using a tissue microarray created at Mayo Clinic, we stained glioblastoma samples from 34 separate patients using immunohistochemistry for galectin-1. A survival analysis revealed a trend towards shorter survival in those patients harboring galectin-1 positive tumors. Abbreviations ATCC: American type culture collection; ECM:

Average corrected absorbance was compared between transfectant and parental cells, using a t-test.ECM attachment assaysThe U87MG human glioma cell line was kept in tissue culture in DMEM (Cellgro Mediatech, Inc.), with 10 fetal bovine serum, and penicillin/streptomycin. For transfection, 2.5x106 cells were plated overnight on a 100 mm round dish. Cells were trans
